TB-UNK-FASTENEB.

To all whom it may concern:

Be it known that I, ALBERT L. Snssrons, a citizen of the United States,and a resident of Bristol, in the county of Hartford and State ofConnecticut, have invented a new and Improved Trunk-Fastener, of whichthe following is a specification. J x

My. invention relates to the class of devices commonly employed tosecure the lid or cover of a trunk, box or the like to the body part,and the object of the invention is to provide a device of this kind thatwhile being extremely strong and eflic'ient is neat in" appearance andmay be cheaply and economically made.

Forms of devices embodying my invention and in the use of which theobjects above set out maybe attained are illustrated in the accompanyingdrawings, .in which Fi re 1 IS a face view of a dowel embodying' myinvention. Fig.2 is a rear view of-the same. Fig. 3 is a View in sectionon plane denoted by line 33 of Fig. 1. Fig.

etis a view'in cross-section onplane denoted by line 44 of Fig. 1. Figs.5 and 6 are respectively face and rear views of a slightly dlfi'erentform of construction embodying my invention.

In the construction of hasp, dowel and like devices commonly employedfor pre- I venting lateral displacementofthe lid 'or cover of'a trunk,box or the like with re spect to the bodypart, the structures arecommonl formed in a single pieceTof cast metal, w ich constructionnecessitates that parts required to withstand little strain must be madeunnecessarily heavy. The

casting method is a common method of producing such structures whichmust be 1 of considerable thickness at certain points to providelugs,catches, etc. In the devices hereinillust-rated and described Ihave provided means whereby the parts composing the structuresenumerated shall be of only the thickness required to withstand thestrains which shall be exerted thereon; the

parts being composed of diflerent pieces of metal, one of which may bestruck to shape from sheet metal and the other of which may be struck toshape from sheet metal or cast as may be desired.

In the accompanying drawings, referring to Figs. 1 to 4, the numeral 10denotes a base plate which'may bestampcd orstruck up from sheet, metalin dies, this plate having the usual openings 11 for fastenings to se-Specification of Letters Patent. t t d g, 27,1912 Application filedSeptember 13, 1909.

cure it inplace. This plate is swelled on the front face as at 12forming a recess 13 on the back of the plate for the reception of theshank of a dowel pin 14. for securing the parts against lateralmovement. This dowel pin or securing member in the form of constructionherein shown, is also made froinsheet metal of concavo-convex form. theshank 15 being formed to fitwithin the recess 13 and being securedagainst removal as by a rivet orxlike fastening 16. The shank fittingthe recess prevents any lateral or longitudinal movement, while therivet 16 prevents detachment. The opposite .end

is formed into a dowel l l'which is adapted,

to enter. a socket-piece in the body part of the trunk, box or likedevice. In thepreferred form of construction the base plate 10 is formedof sheet metal as brass and the dowel may be formed of sheet metalas'steel ,or may be cast to shape, where extra weight and strength is reuired.

In the form of s ructure shown in Figs. 5.

and 6, the base plate '17 is provided with the usual form of attachmentto the trunk or like part and is-flared out as at 18 to provide ahand=hold extending around the '0peni1ig 19 in the plate. In this formof structure a 111g 20 is rovided for engagement of a hasp'from t e bodyof the trunk, and it is therefore a convenient form of construction tocast the part bearing this lug in order to provide the necessarythickness. For this purpose the dowel pins 21 and pro- 'jection 22bearing the lug 20ar'e formed in a single piece, preferably cast toshape, the plate 17 being stamped to form from sheet metal. I

While I have shown and described herein certain structures embodying theinvention,

fastening as it finds'ready application in such a structure, and it willbe found to possess the same advantage in many different structureswhich on account of ce1{-' tain formations must be cast to shape,ias itwill enable such structures to be m'ddc by casting a portion of thestructure only, the other part being formed of sheet metal.

I cla-im- 1. 1} fastening base plate composed o i thin sheet metal, anda dowel formed of another piece of metal of substantially greaterthickness than the base and rigidly secured thereto. I

2. A base plate composed of one piece of metal and having a recessopening from its back surface, and a dowel of concavo-convex formextending into said recess rigidly secured therein and having a partprojecting 10 lo form the dowel proper.

3. A base plate composed of sheetmetal having on its back surface aconcave recess tapering from its outer to its inner end, and a dowelformed of another and substantially thicker piece of metal with one endpointed and shaped to fit Within said recess and secured therein and theother end pointed and shaped to provide a dowel.
